Hi,

Can someone please help me on determining why I am having file conflict issues with WebView2.Core.dll? Below is my csproj file:

@DJRM2021 This is a known incompatibility between EntityFramework and WindowsAppSDK, both of which publish WebView2.Core.dll. There are several workarounds discussed here:
#1856

[DJRM2021]

Maybe we could make a configuration or option in the MSIX tooling to not include WebView2 if the app will not even use it?

Resolving this as a dup of #1856

Reopening, this for tracking WebView2 nuget reference factoring work. Retitled for clarity.
